ABSTRACT:
A door catch which is releasable from inside or outside includes a staple projecting from the door and a caliper (two mutually pivoted levers) having at its free end a hook for engaging the staple. A plate is slidable and rockable relative to the door frame. The inner end of the caliper is pivotally mounted on the door frame. With the caliper folded flat against the frame, the hook is not disengageable for disengagement, the folded caliper must be pivoted out until the hook is spaced from the lip of the staple. This can be achieved manually from inside. If the door is partly opened without disengagement, the caliper opens and the slidable plate can be slid from outside, so that on closing the door a lug on the staple rocks the plate, causing a lug to abut the (closed) caliper and pivot it sufficiently to enable disengagement.
